Abstract: 23,722. Dow Composing Machine Co. and Dow, A. Nov. 28. Type, setting.-Fig. 3 shows in vertical section the operative parts of the machine. The framing comprises a table a<1> on supports a<3>, and two uprights A braced together by cross-stays and carrying the assembly table a<8>, cross-bars a<13>, a<15>, and shaft e<16> &c. The types are in channels b<1> placed side by side in frames or holders b, the lower bar a<9> of which rests in a recess in the table a<8> so that the bottom types are flush with the surface of the table a<8>. The part of the bar a<9> above the table has slots which receive the lower open ends of the type channels. A rear bar b<10> of the type frame is slotted for the passage of the ejectors c<15> which push out the bottom types on to the table a<8>. The ejectors slide in slots a<11> placed in recesses a<10> in the table a<8>, and each ejector is engaged by a slide bar c<14>. The keys C are on arms c' of key levers pivoted at c<1> aud having two other arms c<2>, c<3>. The keys are raised by springs, and are stopped by a cushion bar c<10> attached to an apron a<12> extending from the table a<8>. When depressed, the keys are stopped by a cushion bar c<13>. To each arm c<3> is pivoted a rod c<5> having a lug e<6> engaging a notch in the corresponding bar c<14> when the latter is in normal position. The depression of a key lifts the lug e<6> out of the notch, and the arm c<2> then moves the bar c<14> forward far enough for the shoulder c<19> thereon to be engaged by the blade c<44> on the shaft e<16>, which is driven continuously. The blade c<44> moves the bar c<14> and ejector forward to eject the type. A cushion bar a<25> on which the bars c<14> rest permits them to be depressed if the blade should engage the edge of the shoulder c<19>. When the blade c<44> passes off the shoulder c<19>, the bar c<14> is returned by a trigger c<24> on a lever c<23> pulled by a spring c<27> and stopped by a cushion bar c<28>. The bars c<14> return against a weighted cushion bar c<31> resting on an inclined plane c<30>. Curved recesses in the upper sides of the bars c<14> permit of free rotation of the blade c" when the bars are in normal position. The types are ejected through slots in a bar c<40> pressed down on to the table a<8> by springs. The arm c<2> of any key lever may be provided with means for moving its upper end laterally into position to operate any one of two or three adjacent ejector bars c<14>. This movement may be effected by pins on an arm of a shaft provided with means for rotating it into different positions. Several adjacent channels may thus be charged with the same type, and such channels are all brought under control of the same key. The ejected types are moved along the table a<8> to a central channel a<34>, Fig. 4, by means of type drivers or pushers which sweep over the table. These type drivers are upon the opposite ends of a slide e<2> reciprocated rapidly on the guide-bar E by a lever e<8> &c. operated by a crank on a shaft geared to the shaft e<16>. The movement of the slide is sufficiently rapid to sweep the types singly from either half of the table to the central channel a<34> as fast as they are ejected. The type drivers consist of plates moving over the table and under friction bars g<13> which exert friction on the types as they move. The plates are carried by pairs of plates or arms depending from the slide, and spring-mounted so that they may yield in case of obstruction, such as would occur when a pusher moved two types together. The types are moved against a stop consisting of a pair of sliding dogs, so arranged that they stop the types, moved by either pusher, in position over the channel a<34>. The friction bar g<13>, one on each half of the table is movable vertically, and is raised by arms g<3> of a shaft g<2> into positions varying with the thickness of the type ejected at each operation. The shaft g' has arms operated by rods g<18> pivoted to arms of shafts g<16> rocked by arms g<19> carrying transverse bars having adjustable pins acted upon by inclines on the bars c<14>. The pins are so adjusted that the lifting of the friction bar is in accordance with the thickness of the type ejected. The ends of the rods g<18> are slotted so that each may operate without moving the pin bars &c. of the others. One side wall of the channel a<34> is pivoted to, and pressed by a spring towards, the opposite fixed side wall. As each type is brought over the channel by one or the other of the reciprocating pushers, it is pushed down into the channel by a pusher h<6> on the end of an arm h<1> pivoted at h<2> and oscillated by a double cam h<7> on the shaft e<16>. The type channels may be charged by a distributing-machine, such as that described in Specification No. 26,636, A.D. 1896, and are then placed in the frames b, which are then placed in the machine. The frames b are preferably four in number, and are provided with handles for convenience in removing &c. The blade c<44> is in two parts or sections longitudinally, one of such blades or sections actuating the ejectors which eject the types on to the table to the left of the central channel, and the other blade actuating the other or right-hand half of the ejectors. The blades are so set on the shaft that they operate the ejectors to eject a type when the pushers are at their outward position away from the central channel.
